Weld Lead Calibration provides an increase in arc voltage to help offset the voltage drop based off of inputs of weld cable length and
diameter.

Refer to Section 6-4 for enabling Weld Lead Calibration (WLC)
�
Use of Auto-Set requires WLC or CLC to be enabled.
WLC is a method for overcoming voltage drop when using long cable runs. WLC uses estimated values for the voltage drop based on the ca-
ble size and total length of the positive and negative cables. It provides a voltage increase from the power source to achieve a voltage at the
wire feeder near the display set point.
Factors that affect WLC are the age and condition of your weld cables and the amount of connections used.
